Ok, on va essayer autre chose :
Download NVIDIA Inspector from http://www.guru3d.com/files-details/nvidia-inspector-download.html.
Extract the rar anywhere, and run nvidiaInspector.
3 .Click on "Show Overclocking" in the bottom right.
With the new Overclocking options, we're going to click on "-20" under both Base Clock Offset and Memory Clock Offset.
Once both offsets are showing "-20 MHz" you will click "Apply Clocks & Voltage" and you'll now be downclocked.
You can do this before you start the game or even while it's open. The settings that you apply will remain that way until you hit Apply Defaults.
I've been able to play with no dumps or BSODs for a good hour. Hopefully it will be patched soon so I can use my GPU's full clock speed.
